Abstract

The invention discloses a computer aided design device for the integration performance optimization of an airliner and a fanjet and a method thereof, which belong to the technical field of aerial engines. The design device is characterized in that an input device, a central processing unit, an internal storage module, a storage device and a display device are connected through a data line. The internal storage module comprises a system program library, a system interactive operation window, a fanjet design module, a fanjet size/weight/resistance estimating module, an airliner flying performance simulation module and an airliner/fanjet integration performance optimizing module. The design device and the method can quickly and fully consider mutual requirements and effect of the technical parameter of the airliner and the fanjet, conduct performance matching calculation and evaluation of the existing airliners and the existing engines and performance matching calculation, optimization and evaluation research of the newly designed air liners and engines.
